Hi, @Alisa if you are on a desktop pc, look under Log Out at the top right corner - it will say 'Fractional' just click on the triangle at the right of it to change to decimal instead.
Failing that (if different for phone users etc.) a good tip I learnt for ALL bookies, is to put a 1.00 bet amount in the betslip (WITHOUT PLACING IT), and whatever the 'possible win' amount is, are the actual decimal odds.
Try it now, for example 12/1 would show as £13.00 possible winnings - therefore the decimal odds would be 13.00.
Don't forget to remove the £1.00 bet from the betslip afterwards
